COLD ROLLING AND RECRYSTALLIZATION TEXTURES OF HIGH-PURITY IRON.

Zone melted iron specimens with different grain sizes (40 vs 270 mu ) were hot forged and hot rolled into 2 mm sheet, which was then further reduced to 0. 5 mm thickness by cold rolling 75%. This was followed by isothermal salt bath annealing at 500 or 575 C. The effect of grain boundaries on cold rolling and recrystallization textures was determined by x-ray pole figure measurements and optical and electron microscopy.
